[Japanese researchers develop all-solid-state air battery is expected to be used in portable electronic devices] May 25, according to a joint communique issued by Yamanashi University and Waseda University in Japan, the research team of the two sides developed an all-solid-state air battery with proton exchange membrane as electrolyte and organic matter with redox activity as negative electrode. This kind of battery can be charged and discharged repeatedly, light and safe, and can also be used in the bending state, so it is expected to be used in portable electronic devices. The relevant papers have been published in the German academic journal Applied Chemistry International Edition.
